FA7MX-SERIESIndoor Field Disturbance Sensor

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 March 27, 2001 RE: FCC ID FA7MX-SERIES Dear Motomu, I have a couple of items that must be cleared up on the documentation for this field disturbance sensor before I can proceed. 1.) Internal Photographs: It is an FCC requirement that all RF shielding be removed for photographs. Please resubmit. In addition, I find the photos a bit small. Please submit just one photo per page and as large as practical. 2.) Please provide test setup photos as an extraction from the test report. Do not submit the test report twice. 3.) The Block Diagram is not of sufficient detail to qualify for Confidentiality. Please submit new block diagram, or de-list the existing block diagram by submitting a new confidentiality request. 4.) The operational description is a bit weak. Please provide more detail as to how the circuitry performs it’s functions. If this is to be Confidential, it can be requested. All other items on the Application appear to be in order. Please resubmit the requested documents through the AmericanTCB website. William H. Graff Examining Engineer President and Director of Engineering The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information within 30 days of the original e-mail date may result in application dismissal pursuant to Section 2.917(c). Correspondence should be considered part of the permanent submission and may be viewed from the Internet after a Grant of Equipment Authorization is issued. Please do not reply to this correspondence using the email reply button. In order for your response to be processed expeditiously, you must attach your answers to email correspondence. Reply to the examiner at the email address shown below. Also, please note that partial responses increase processing time and should not be submitted.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 March 30, 2001 RE: FCC ID: FA7MX-SERIES My final review produced one nagging doubt about this application. 1.) 15.245 (b)(1)(i) specifies that field disturbance sensors used exclusively within a building or to open building doors are limited to a maximum field strength of 25mV/meter (68 dBuV/m). The Users Manual specifically warns against outdoor installation. Please justify William H. Graff Examining Engineer President and Director of Engineering mailto:[email protected] The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information may result in application termination.

MX-40 Technical description MX40 has a microwave Doppler (MW) detector and a Passive infrared (PIR) detector. When both detectors detect a human at the same time, MX-40 outputs an alarm output from terminal. And LED indicates alarm conditions. MW detector transmits and receives S-band microwave (2.45 GHz). If there is a moving human in the detection area, it causes changes in received microwave frequency (Doppler effect). MW detector outputs signals when there are such changes. PIR detector detects temperature contrasts between human body and back ground in the detection area. Block diagram description MW SENSOR MW SENSOR transmits and receives S-band microwave (2.45 GHz). If there is a moving object in the detection area, it causes changes in received microwave frequency (Doppler effect). MIXER outputs signals when there are such changes. Fundamental microwave frequency is generated by OSC, and Microwave is emitted from the antenna (Inverted L type antenna /4) through MIXER. The reflections of Microwave at objects in the detection area are received at the antenna, and mixed at MIXER with fundamental microwave frequency. If there is human moving in the detection area, the microwave frequency is added with moving speed of the human for Doppler effect. Then MIXER outputs the Doppler signals (110HZ) to AMPLIFIER. AMPLIFIER Signals from MW SENSOR are amplified at AMPLIFIER (90dB). COMPERRATOR Amplified signals are compared with the threshold level at COMPERATOR. If the signal exceeds the threshold level, the detection signal shall be output to TIMER. TIMER The detection signal is hold for the predetermined period at TIMER. The switch connected with TIMER in CUSTOM IC is activated by the detection signal from TIMER. PIR signals are accepted during this period. PIR SENSOR Infrared radiations from human body are focused with optics and received with pyro- element. Pyro-element converts infrared radiations to electrical signals. AMPLIFIER Signals from PIR SENSOR are amplified at AMPLIFIER. COMPERATOR Amplified signals are compared with the threshold level at COMPERATOR. If the signal exceeds the threshold level, the detection signal shall be output to PULSE COUNT. PULSE COUNT During the switch between COMPERATOR and PULSE COUNT is ON, PULSE COUNT counts the signals from COMPERATOR. If PULSE COUNT counts over the predetermined counter in the predetermined period, the detection signal shall be output to OUTPUT TIMER. The predetermined counter can be selectable 2 or 4 with PULSE COUNT SWITH. OUTPUT TIMER The detection signal is hold for the predetermined period at OUTPUT TIMER. RELAY DRIVE and LED DRIVE activated during this period. RELAY DRIVE, LED DRIVE The alarm output relay and the LED for alarm indication shall be activated during the period of OUTPUT TIMER activation.

The sample calculation is as follows : FS = RA + AF + CF + AT - AG where FS = Field Strength RA = Receiver Amplitude AF = Antenna Factor CF = Cable Factor AG = Amplifier Gain Assume a Spectrum Analyzer reading of 92.3 dB V is obtained. The antenna Factor of 28.8 dB, and Cable Factor of 6.7 dB is added. The Amplifier Gain of 34.5 dB is subtracted, giving a field strength of 93.3 dB V/m.
